Kinetic and sound energy

•Kinetic
energy

•Moving
things have kinetic energy. The heavier a thing is and the faster it moves the
more kinetic energy it has. All moving things have kinetic energy, even very
large things, like planets, and very small ones, like atoms.

•Sound
energy

•A
vibrating drum and a plucked guitar string transfer energy to the air as sound.
Kinetic energy from the moving air molecules transfers the sound energy to your
eardrum.
